Slinkyrose-
I think that you and your son might benefit from counseling. It sounds as if he is using the video game to escape from reality, and he may need extra help facing whatever it is that he is afraid of facing. Video game addiction is a real problem for many people, and it can be very destructive. I'm not sure, but I suspect that there may be 12 step programs for video game addicts. I really think you need to address this now, as once your son turns 18, he's a legal adult and there's not much you can do.
Life is all about balance, and there isn't a good balance in this situation. Video games are not evil, but it seems clear that your son is having a problem with self regulation that requires intervention. He might be angry about it now, but if you are proactive, he might be very grateful to you later in life.
best wishes,
